Splicing Device Holding Phase for Tape Affixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional splicing devices face issues with the insufficient affixation of splicing tape to carrier tapes due to inadequate affixation force, leading to a risk of the splicing tape peeling off, which can be mitigated by extending the pressing time or modifying the cam groove, but these solutions increase cycle time or device size.
Innovation Solution
A splicing device with a positioning system to align carrier tapes, pressing members to apply splicing tapes, and a control mechanism to temporarily stop the driving action in a pressing state, ensuring extended pressing time and reliable affixation of splicing tapes to carrier tapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cam drive mechanism operates at low speeds to extend pressing time, then the affixation reliability of splicing tape is improved, but the cycle time of splicing increases
Solution Approach 1:
The pressing action is divided into periodic phases: a rapid pressing phase followed by a holding phase where the cam mechanism pauses. This periodic action allows the splicing tape to be quickly pressed onto the carrier tape and then held in place for sufficient time to ensure proper affixation, without requiring continuously slow operation throughout the entire cycle
Solution Approach 2:
The cam mechanism performs preliminary rapid positioning and pressing of the splicing tape onto the carrier tape ends, establishing initial contact and alignment. This preliminary action prepares the system for the subsequent holding phase, ensuring that the affixation process begins with proper positioning before the extended pressing time is applied
2Reliability
If the cam groove shape is modified to extend pressing time, then the affixation reliability of splicing tape is improved, but the device size increases
Solution Approach 1:
The invention modifies operational parameters of the existing cam mechanism rather than changing its physical dimensions. By adjusting the cam groove profile to create a holding phase in the motion cycle, the pressing time is extended without increasing the cam size or overall device volume
Solution Approach 2:
The cam groove is designed to create dynamic variations in pressing force and timing, with phases of rapid pressing followed by a holding phase where the pressing force is maintained. This dynamic operation allows extended effective pressing time without requiring larger mechanical components
3Reliability
If the affixation force of splicing tape is increased, then the affixation reliability is improved, but the risk of carrier tape deformation increases
Solution Approach 1:
The pressing force is applied periodically with distinct phases: an initial rapid pressing phase that establishes contact, followed by a holding phase with sustained but controlled force. This periodic application allows the splicing tape to bond properly without subjecting the carrier tape to continuously high forces that could cause deformation
Solution Approach 2:
The system performs preliminary positioning and alignment of the splicing tape with the carrier tape ends before applying full pressing force. This preliminary action ensures proper alignment is established, allowing the subsequent affixation force to be applied efficiently without requiring excessive force that could deform the carrier tape

AI summary
A splicing device includes a drive device configured to cause a pressing surface of a first pressing member and a pressing surface of a second pressing member to reciprocate relatively towards and away from each other through a series of actions and a control device configured to stop temporarily the series of actions of the drive device in a pressing state where the first pressing member and the second pressing member press a first splicing tape and a second splicing tape against a first carrier tape and a second carrier tape through the series of actions of the drive device.
